Side effects after radiotherapy of age-related macular degeneration with the Nijmegen technique.

BACKGROUND: In a randomized trial concerning radiotherapy for age-related macular degeneration, fluorescein angiograms were taken of controls and patients. In this study the frequency of side effects in eyes receiving radiotherapy with the Nijmegen technique is compared with the findings in the eyes of controls. METHODS: Patients receiving treatment were irradiated by two isocentric photon beams in four fractions of 6 Gy that were directed to the macular area at 30 degrees and -30 degrees with regard to the optical axis. The most recent fluorescein angiograms of the randomized eyes (32 treated and 31 control eyes) were scored by two independent researchers, using a scoring form with nine features of radiation retinopathy: nonperfusion, macular edema, microaneurysms, retinal hemorrhages, cotton-wool spots, perifoveal telangiectasis, vascular sheathing, retinal neovascularization, and radiation-associated choroidal neovasculopathy. The results were graded as: no retinopathy (grade 0), mild retinopathy (grade 1), moderate retinopathy (grade 2), and severe retinopathy (grade 3). RESULTS: In the treated group 6 patients (18.8%) were grade 1, 10 patients (31.2%) were grade 2 and 7 patients (21.9%) were grade 3. In the control group 9 patients (29.0%) were grade 1, 11 patients (35.5%)were grade 2 and 2 patients (6.5%) were grade 3. There were no patients with retinal neovascularization. CONCLUSION: With the Nijmegen technique a relatively high dose of radiation can be applied to a small retinal area. In only a minority of cases does some evidence of radiation retinopathy occur.

Use of intravitreal triamcinolone acetonide injection in unilateral idiopathic juxtafoveal telangiectasis.

Idiopathic juxtafoveal telangiectasis (IJT) is one of the primary retinal telangiectasia that can result in visual impairment attributed to resultant cystoid macular oedema and rarely, choroidal neovascularization. The authors herein report successful treatment using intravitreal triamcinolone acetonide in a case of unilateral IJT that did not respond to prior laser photocoagulation. Serial optical coherence tomography was used to monitor the effectiveness of intravitreal triamcinolone acetonide in the treatment of IJT.

The differential diagnosis of crystals in the retina.

Crystalline deposits in the retina may be associated with a wide variety of systemic disorders such as oxalosis, cystinosis, hyperornithinaemia and Sjögren-Larsson syndrome. Refractile crystalline deposits may also be a manifestation of drug toxicity like the antineoplastic agent tamoxifen, the anesthetic methoxyflurane and the oral tanning agent canthaxanthine. Crystals may also occur in drug abusers who inject multiple crushed tablets of methadone or meperidine intravenously (talc retinopathy). The differential diagnosis of retinal crystals also includes primary ocular diseases like Bietti's crystalline retinopathy, calcified macular drusen, idiopathic parafoveal telangiectasis and longstanding retinal detachment. This article will review the most common causes of crystalline retinopathies, their etiologies, pathologies and clinical characteristics.

Selective photocoagulation in Coats' disease: ten-year follow-up.

PURPOSE: The diagnostic hallmark of Coats' disease is development of "light bulb" telangiectasis in the retinal periphery, leading to posterior pole intraretinal and subretinal exudation. Even after complete obliteration of all abnormal vessels and resorption of all exudates, follow-up examinations are mandatory for several years. METHODS: We retrospectively analyzed the charts, pictures and/or fluorescein angiographies of a series of 32 consecutive patients, in which the diagnosis of Coats' disease was made. All patients underwent selective photocoagulation of the telangiectasis using a yellow-dye laser. Efficacy of treatment was monitored with drawings and/or fluorescein angiographies. RESULTS: All our patients had unilateral disease, with macular involvement and exudative retinal detachment. Visual acuity improved in one patient, decreased from light perception to blindness in another, and was unchanged in the remainder. CONCLUSIONS: This is the first report of anatomical benefits from treatment with a yellow-dye laser (i.e., selective photocoagulation without cryotherapy or drainage) despite the presence of a severe form of Coats' disease. Our young Coats' patients responded quickly to treatment. With successful obliteration of the abnormal vasculature, exudates began to absorb in about 4 to 8 weeks although, in some cases, 10 to 12 months were needed to obtain resolution of the exudative detachment. Poor visual outcome of 20/100 or worse was common. In Coats' patients, the key issue is continuous control and long-term follow-up.

Retinal vascular abnormalities in facioscapulohumeral muscular dystrophy. A general association with genetic and therapeutic implications.

Because of occasional reports of exudative retinal detachment with facioscapulohumeral muscular dystrophy (FSH) and deafness, we sought to determine by fluorescein angiography whether there is any general relationship between FSH muscular dystrophy and retinal vascular disease. Peripheral retinal capillary abnormalities, comprising telangiectasis, closure, leakage and microaneurysm formation, were demonstrated by angiography in 56 out of 75 individuals with clinical or genetic evidence of FSH. Only 3 patients had relevant ophthalmoscopic abnormalities of the posterior pole and in only 1 was there consequent visual loss. This study included one FSH family in which the propositus was treated for exudative retinopathy and 13 other subjects had telangiectasis, and 8 cases (including 3 parents of apparently 'sporadic' FSH cases) in which fluorescein angiography confirmed the abnormal genotype, even though clinical examination of skeletal muscle revealed no clear abnormality. There was no correlation between the severity of the muscle disease and the extent of the retinal vascular abnormality. Visual complications of telangiectasis, although rare, may present early in life and before there is overt evidence of muscle disease. Since visual loss may be preventable, ophthalmic examination should be undertaken on infants at risk of having the abnormal gene. The findings support the hypothesis that retinal capillary abnormalities are an integral part of the FSH muscular dystrophy syndrome and raise the question as to whether analogous capillary abnormalities could be implicated in the pathogenesis of FSH muscle disease.

[Myelinated nerve fibers associated with cilioretinal artery occlusion].

Although the myelinated nerve fibers are considered as benign, cases associated with retinal vascular abnormalities (telangiectasis, neovascularization, vascular occlusions) have recently been reported, suggesting a possible pathogenic correlation between these elements. Our observation presents a 44-year-old patient, with a sudden decrease of visual acuity in the right eye, discal and peridiscal myelinated nerve fibers, associated with cilioretinal artery occlusion. The general clinical and laboratory examination, except for a drug stabilized arterial hypertension, did not reveal other local or general embolic factors. One year later, the decrease in visual acuity had remained unchanged and the area of the myelinated nerve fibers had diminished. Based on the association between the myelinated nerve fibers, the cilioretinal artery occlusion, the young age of the patient, and the absence of other local or general embolic factors, we consider there is a possible pathogenic correlation between these elements. The action of the myelinated nerve fibers can be explained by a mechanical compression, with the disruption of the cilioretinal artery route, a structurally vulnerable artery.
